How to use Spring Security with graphql-dgs-webflux-starter

[cnolte]

I'm new to DGS so this might be a stupid question. But how do I add Spring ReactiveMethodSecurity to an Endpoint? I was expecting that something simliar like the following works:

@DgsComponent
class UsersDataFetcher(private val userService: UserService) {

    @PreAuthorize("isAuthenticated()")
    @DgsQuery
    fun users(): Mono<MutableList<User>> {
        return userService.getAllUsers().collectList()
    }
}

This resolves an error: "Can't resolve value (/users) : type mismatch error, expected type LIST".

Also, are you returning a Mono<MutableList> instead of a Flux in purpose?

[cnolte]

Flux or Mono is not supported as return type

If i'm getting data from a database with r2dbc, how do I map the Flux/Mono types with the dgs data fetchers?
